MACHINE FOR DISINTEGRATING FIBROUS MATERIAL.

SPECIFICATION formingpart of Letters Patent No. 265,117, dated September26, 1882. Application filed February 25, 1882. (No model.)

To all whom it may concern Be it known thatI, FRANZ LiiFtr, a citizenofthe United States, residing at New Orleans, in the parish of Orleansand State of Louisiana, have invented certain new and usefulImprovements in Machines for Disintegratin-g Fibrous Material; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in machines or apparatus fordisintegrating the fibers of jute, wood, and other fibrous material orsubstances; and the object is to produce a machine that will do thedisintegrating in a more thorough as well as economical manner than hasbeen done heretofore to my knowledge.

The invention consists in the construction and arrangement of certainparts, as will be more fully described hereinafter, reference bein g hadto the accompanying drawings and the letters of reference markedthereon.

Like letters refer to like parts in the several figures of the drawings,in which- Figure 1 represents a side view of my machine, partly incross-section. Fig. 2 is a plan view of the bed plate or stone. Fig. 3is a side view of the revolving stone.

In thedrawings, A is the bed-plate, made preferably of iron and in fourpieces, which are bolted together by means of downwardprojecting flangesa, through which suitable bolts pass and secure the pieces together. Theface of this bed-plate is provided with a large number of short points,I), over the entire surface and cast upon the four pieces. The object ofthese points is to roughe'n the surface and prevent the jute or othermaterial to be operated upon from slipping or bein g carried around bythe revolving stone. The bed-plate is firmly secured to a solidfoundation, B, of stone or wood, and to this is secured a step, G, inwhich an upright shaft, D, is stepped and revolves. This shaft ispreferably made of wood and strengthened by wrought bands at intervals,although it may be made of iron. At its upper end the shaft revolves ina suitable journal, E, bolted to the ceiling or girdinto which thepinion G meshes. This pinion is secured on a shaft, H, to which motionis imparted by a proper-sized pulley, I, which may be a tight and loosepulley, if desired. To the bedplate, both at its outside and inside, isfirmly fastened a rim or upward pro jecting flange, c and 61, forming anannular basin, into which the material to be operated upon is placed,with water to soften it. An outlet-pipe, c, is arranged at one side,through which the water can be withdrawn when deired, and a strainer maybe placed over the inner end. A valve is placed in the pipe to close it.At a proper distance above the bedplate is firmly secured to the shaft Da horizontal arm or shaft, K, preferably made of square iron. Upon theouter rounded end of the shaft K a roller or revolving stone,-L, isattached, so as to revolve upon said shaft. This roller is made of anysuitable material, but I prefer to use stone which is faced on its sideswith cast metal, also provided with a number of points or roughenededges, as shown in Fig. 3. A suitable spider, M, to which the stone issecured, has a hub,f, which may be lined with a bushing, so it can'bereplaced when it is worn out, and revolves on the shaft K.

'If desired, scrapers may be attached to the horizontal shaft, by whichthe material is pushed or carried in front of the revolving stone.

The operation is as follows: The material beingplaced in the annularbasin, with a proper amount of water, motion is imparted from any motivepower to the pulley Iand its shaft, which rotates the pinion G, and thisstarts the bevel-wheel F, which in turn gives motion to the uprightshai't'D, and by it the stone L is revolved on the bed-plate and crushesthe material and disintegrates the fibers, which are used for variouspurposes, such as packing, wool fiber, Ste.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. In a machine for disintegrating fibrous IOO substances, the bed-plateprovided with points I) on the surface, and made in sections havingdownward-projecting flanges a, by which and suitable bolts the sectionsare secured together, substantially as described.

3. In a machine for disintegrating fibrous substances, the bed-plate A,having points I), and annular rims o d, in combination with a roller, L,attached to a horizontal shaft, K, secured to the shaft D, substantiallyin the manner shown, and for the purpose specified.

4. In a machine for disintegrating fibrous substances, the roller L,consisting of a spider,

' to which the stone face is secured, andhaving its sides faced withmetal provided with points, as and for the purpose set forth.

5. A machine for disintegrating fibrous substances, consisting of a bedplate, A, with points I), an annular basin, an upright shaft,

D, to which the horizontal shaft K is secured, 20 having a roller, L,with roughened sides, and operated by means of asuitable gearing, allconstructed and arranged substantially as specifled.

In testimony whereof I hereby affix my sig- 25 nature in presence of twowitnesses.

FRANZ LUFT.
